SELF-LIGHTING GAS-BURNER.

SPECIFICATION forming part of Letters Patent No. 627,631, dated June 27, 1899. Application filed November 26,1897. Renewed. May 26,1899. Serial No. 718,426. (No model.)

To all whom it may concern:

Be it known that I, J HN A. WILLIAMS, a citizen of the'United States, residing at New York, (Brooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in Self-Lighting Gas-Burners, of which the followingis a specification.

My present invention relates to improvements in automatic lighting devices for gasjets,-the constructionand advantages of which will be hereinafter set forth, reference being had to the annexed drawings, in which- Figure 1 is a perspectiveview of the device, the parts being shown in the relation which they occupy when the flame is not burning; Fig. 2,.a similar View showing the parts in their relativepositions when the gas is lighted and Fig. 3 a top plan View.

The object ofmy invention is to provide a simple and efficient automatic igniting device for gas-jets,and the forms shown are illustrative of an embodiment of my invention broadly claimed in application Serial No. 659,872.

In the drawings, A indicates the burner, to which is attached, just below the tip, a thermostatic coil B. The'coil comprises two strips of metal having different coefficients ofexpansion so united that as the coil is heated it will unwind. As shown, the coil occupies a horizontal position or is in a plane at right angles to the axis of the burner. The outer or free end of the coil is bent at right angles, forming a shoulder or abutment O, and from this point an arm D extends upward in line with the opening in the tube when the parts are in the relation shown in Fig. 1 Secured to the upper end of this arm is a basket E, containing platinum-black or other substance possessing the power of absorbing or condensing oxygen and causing the gas to ignite when it comes in contact therewith. Instead of the basket any other suitable means may be'employ-ed to bring about the desired result.

To one side of the burner, in line with the opening in the tube, I provide a stop F, which extends out in the path of the coil and, coming in contact with the end thereof, holds the arm D in alinement with the tip, and consequently insures the gas coming in contact with the basket as it issues from the burner. A similar stop G is provided at a point ninety degrees from the stop F, so that when the gas is ignited and the coil expands the shoulder C will come in contact with the stop G and prevent further movement of the coil. The relation of the parts is shown in Fig. 2, and

it will be noted that the basket stands to the flat side of the flame and out of contact therewith, so that the igniting material will not become deteriorated by direct contact with the flame. The stops F and G always insure the parts being held in their proper position.

The operation of the device will be readily understood. When the gas is turned on, it will come into direct contact with the basket and the igniting material contained therein and will immediately be ignited. So soon as this occurs the heat generated by the flame will act upon the thermostatic coil and cause it to expand, carrying the arm D and the basket E around until the shoulder 0 comes in contact with the stop G, in which position the coil will be held until .the gas is turned off. Immediately thegas is turned off the coil begins to cool, and the basket or igniting device E willreturn to its former position, as indicated in Fig. 1, ready to again ignite the gas as it issues from the jet.

Having thus fully described my invention, what I claim is-- 1. In combination with a gas-burner, a thermostatic coil connected thereto and encircling the same at its upper end, and an igniting substance carried by the free end of the coil in line with the opening in the burner.

2. In combination with a gas-burner, a thermostatic'coil connected thereto and encircling the same at or near its upper end, an igniting substance carried by the free end of the coil, and stops to limit the movement of the coil, substantially as and for the purpose described.

3. In combination with a gas-burner, a'thermostatic coil connected thereto and encircling the same at or near its upper end, an igniting substance carried by the free end of said coil,

a stop in line with the opening in the burner, and a second stop placed at approximately ninety degrees to the first stop.

4. In combination with a gas-burner, a thermostatic coil B connected thereto and encircling the same at or near its upper end, a shoulder 0 formed at the outer end of said coil, arm D, igniting substance E carried by the upper end of said arm, and stops F and G connected to the burner, substantially as and for the purpose described.

5. In combination with a gas-burner, a thermostatic coil lying in a horizontal plane around the upper end of the burner, and an igniting substance carried by the outer end of the coil normally in line with the opening in the burner, whereby when the gas is turned JOHN A. W'ILLIAh IS.
